RATINGS & SPECIFICATIONS

GENERAL INFORMATION

The Hubbell 600 A 35 kV Deadbreak T-body offers an easy and reliable method of terminating and splicing main feeder circuits. The Deadbreak T-Body is a fully shielded, molded rubber connector. The Deadbreak T-body is designed to terminate power cables with copper or aluminum conductors ranging in size from #2 AWG to 1250 kcmil. It may be installed on any 600 A rated apparatus bushing that meets IEEE Std. 386 Interface 13. Cable adapters accommodate power cable insulation diameters from 0.530 to 1.935 inches. The Hubbell Deadbreak T-body has been designed and tested to meet the requirement of IEEE Std. 386 and IEEE Std. 592. Conformance to the industry standards ensures mechanical and electrical interchangeability with other manufacturer’s products that are also in conformance with these standards.
